I LUIGI MARSILII, OF WEST CHESTER, PENNSYLVANIA.

1 CULTIVATOR.

Specification of Letters Patent.

Patented May 16, 1911.

Application filed. October 27, 1909. Serial No. 524,962.

To all whom it may concern:

Be it known that I, LUIGI MARsILII, subject of the King of Italy, residing at \Vest Chester, in the county ofChester and State of Pennsylvania, have invented certain new and useful Improvements in Cultivators, of which the following is a specification.

This invention relates to certain new and useful improvements in cultivators.

The object of the invention is to provide a wheeled cultivator capable of vertical adjust-ment and equipped with means for varying the depth of the furrows cut. a

Reference will be had to the accompanying drawings forming a part of the specification and whereby like numerals of reference designate corresponding parts throughout the several views, in which Figure 1 is a top plan view of the cultivator. Fig. 2 is a side elevation thereof. Fig. 3 is a fragmentary view in front elevationof the traction wheel adjusting structure, and Fig. 4 is a detail view of the pole coupling.

Reference numeral 1 designates the vehiclebody in the form of a cross beam, to the opposite ends of which are attached vertical side plates or standards 2. The body is supported and conveyed by wheels 3 journaled on stub-shafts or axles 4, the latter being equipped each with a vertical extension or shank 5; these extensions are secured to the said standards 2 by yokes 6 straddling said extensions and having their ends passing through the said standards 2 and secured by nuts 7. The yokes are disposed diagonally as seen in Fig. 2 and when clamped by said nuts 7 securely hold the extensions 5 in their vertically adjusted position. The extensions are prevented from being displaced laterally by upper and lower pins 8 projecting from the standards 2 and engaging opposite sides of the axle extensions.

Riveted to the standards 2 at the upper ends thereof, are clips 9 through which weight levers 1O adjustably pass, the latter being secured against the standards 2 by set screws 11 which are threaded in said clips. A weight 12 is adjustably mounted on each of said levers 10.

Bolted to the upper face of the body or cross beam 1 and extending rearwardly are spring cultivator teeth 14, the alternate teeth being of greater length than the intervening ones. The two end teeth project be yond the front edge of the cross beam and are apertured as at 15, to receive the ends of chains 16, the latter being engaged centrally with a hook 17 beneath the vehicle tongue 18, the tongue being coupled to the hooked projecting end 19 of the middle harrow tooth. To prevent the pole ring 20 from being accidentally disengaged from said hook 17, the latter is equipped with a pivoted retainer 21. The object of the chain 16 is to assist the vehicle in making turns.

Theseat 22 is mounted on a U-shaped support 24;, the free ends of which are slotted as at 25', and these ends are bent substantially at right angles and adjustably secured to the upper face of the cross beam by means of bolts 26 passing through the slots 25, said free ends being located on opposite sides of the central cultivator tooth.

In operation, the horses are hitched up to the trees 32, of the cultivator, to draw the latter over the soil to cut furrows therein. To vary the depth of the cut, the axle extensions are adjusted in yokes 6 thereby regulating the height of the cross beam from the ground and the angle at which the cultivator teeth points enter the ground. B adjusting the weights 12 and the seat 22 to throw the weight rearwardly, the depth of cut by the teeth 14 will be increased, and by shifting the seat forward and reversing the weights to a position in front of the cross beam, the depth of the cut will be decreased. Of course it will be obvious that the different effects may be produced by different relative adjustments of the seat and weights. In some cases it will be desirable to arrange one weight lever in front and the other in the rear of the cross beam, and one end of the cross beam will be closer, to the soil, whereby, these combined adjustments will cause the teeth 14 at one side to penetrate the soil to a different depth from the teeth at the other side.

Having fully described the invention, what is claimed as new and useful and desired to be secured by Letters Patent is:

1. A cultivator, comprising a cross beam, teeth attached thereto, uprights at each end of the cross beam, wheels, axles therefor provided with vertical extensions, diagonally disposed yokes each having its ends passing. through one of said uprights, said axle extensions passing through said yokes and being adjustably secured thereby, and pins 011 said uprights, one engaging each side of said axle extensions.

2. A two wheel cultivator comprising a cross beam, uprights carried by the ends thereof, axles, wheels journaled thereon, uprights carried by the inner ends of the axle and being adjustably secured to the beam uprights to permit vertical adjustment of the cross beam, loops on the upper ends of the beam uprights, a weight beam adjustably secured therein and being capable of reversal, a weight adjustably mounted on the said weight beam, a seat and harrow teeth extending rearwardly from the cross beam, andhdraftrigging connected with the harrow teet In testimony whereof I afiix my signature in presence of two witnesses.

LUIGI MARSILII.
